np_any_axis1

dtaianomaly.utils.np_any_axis1(x)[source]

Numba implementation for np.any(x, axis=1).

Iterates over the rows of the given matrix and applies a logical OR to it. Thus, if any value in row \(i\) is True, then the value at position \(i\) in the output will be True.

Parameters:

xnp.ndarray of shape (N, M): The array on which the numpy-call should be applied.

Returns:

np.array of shape (N,): Identical as np.any(x, axis=1).

Examples

>>> import numpy as np
>>> from dtaianomaly.utils import np_any_axis1
>>> np_any_axis1(np.array([[True, True], [True, False], [False, True], [False, False]]))
array([ True,  True,  True, False])
